naperlou, the research has only just begun, so you're right that no one is doing this yet. The photos show prototypes, no doubt the ones shown to the NSF. The fact of who is involved also piqued my interest: the concentrated brainpower here is quite high, and many of the people involved have already done some pretty amazing things in robotics.
I agree with your skepticism to some extent, Al and Beth. By looking at the background data, it appears that the researchers have used the words "design and customize" to really mean "customize" on a couple of different levels. What intrigued me about this, aside from the robot angle, is that it's quite in line with other developments Beth has written about regarding the use of blueprints by consumers to 3D print household items. This just takes that a couple steps farther with slightly more complex machines.
Ann, from the pictures I can see that this is a primitive device. Where are the joints? This will not have the mobility that is discussed.
What I really don't understand is the use of the term "democratize". To do what these researchers talk about you could certianly use a wheeled vehicle to better effect. What is the NSF doing funding this? If you could make really useful robots from just a specification language and a 3-D printer then people would be doing it.
Beth, I agree with you on the commercialization aspects of this project. Many of us would support NSF funding for research activities but the focus on "developing a desktop technology that lets the average person design, customize, and print a specialized robot in a few hours" is curious. Certainly the average person isn't going to produce results in terms of research funding, but I assume the project has primarily been funded on its merits as significant research.
Very cool initiative, but I have to wonder about the complexity of creating a 3D printer that is capable of allowing the average consumer to actually produce something that is so complex is terms of functional behaviors, not just physical form. It's one thing for a 3D printer to effortlessly crank out a screw or a bolt or some other physical piece of hardware that can fix a household appliance, but doesn't perform any movement. It's quite another to 3D print an entire robot that has motion to unscrew a jar or open a door.
No doubt it's possible in a research lab; I'm just wondering about the realities of commercialization on a grander scale.
How 3D printing fits into the digital thread, and the relationship between its uses for prototyping and for manufacturing, was the subject of a talk by Proto Labs' Rich Baker at last week's Design & Manufacturing Minneapolis.
How can automakers, aerospace contractors, and other OEMs get new metal alloys that are stronger, harder, and can survive ever higher temperatures? One way is to redesign their crystalline structures at the nanoscale and microscale.
Although a lot of the excitement about 3D printing and additive manufacturing surrounds its ability to make end-products and functional prototypes, some often ignored applications are the big improvements that can come by using it for tooling, jigs, and fixtures.
